Seemed to work well with resolving a flea outbreak and preventing future ones. However, it would cause excessive ear-scratching and head-shaking in my dog for a few days after. The vet didn't seem to think this was a common side effect, but suggested we move to a different brand.

I put the medication on Scotland as directed. While I didn’t expect it to work immediately, I also didn’t expect to see more fleas than we started with. I treated all the animals in my home as well as my carpets and washed their bedding. Nothing is helping.

Wish I had been using Advantage II on Jax! Before using i didn't know how the fleas had chewed him up, I thought it was an allergy which he got shot and I bought so many tubes of anti-itch cream. bought a flea comb and so many fleas! Vet suggested Advantage, using now...none 1 or 2 fleas!! Jax doesn't scratch and scratch anymore and he can get some sleep and me too! I am so happy for him!

This is an inexpensive way to prevent fleas but it stinks

I used it on my doodle but the smell was making me sick so I had to bath her. I am going to have to go back to pills.

I used to use this brand hen i lived in the suburbs and it worked great for fleas and didn't notice ticks at all. Once we moved up north to more deep woods it didn't seem to do much for ticks, we kept finding engorged ticks on the dog and several getting embedded.
